Presenting tags of a tag cloud in a more understandable and visually appealing manner

ABSTRACT

A method, system and computer program product for presenting tags of a tag cloud in a more understandable and visually appealing manner. Tags of a tag cloud that are associated with an object (e.g., web page) are retrieved. The retrieved tags are then assigned to parts of speech (e.g., noun, verb, adjective, adverb). Combinations of the tags are then generated based on the parts of speech assigned to the tags. For example, the combinations of the tags may be based on a template, such as &lt;NOUN&gt; &lt;VERB&gt; &lt;ADJECTIVE&gt;, &lt;PRONOUN&gt; &lt;VERB&gt; &lt;ADJECTIVE&gt;, &lt;PRONOUN&gt; is &lt;ADVERB&gt;&lt;VERB&gt; and so forth. The combinations of the tags are then presented after determining the layout to display the generated combinations of tags. Since the tags of the tag cloud are presented in a combination based on the parts of speech assigned to the tags, the tag cloud is more understandable and visually appealing.

TECHNICAL FIELD

The present invention relates generally to tag clouds, and more particularly to presenting tags of a tag cloud in a more understandable and visually appealing manner.

BACKGROUND

Tag clouds are visual depictions that allow users to easily see the content of an object or tag source, such as a webpage, news article or video. A tag cloud contains a set of related tags, where each tag is a keyword pertaining to the object or tag source. The tag cloud emphasizes the tags that are more popular or are associated with more frequently used keywords pertaining to the object or tag source, such as by increasing the tag's font size, font color, etc. The tags in the tag cloud may be hyperlinked to keywords within the source for the user's convenience.

Currently, the tags of the tag cloud are presented in a predefined manner, such as in alphabetical order, in order of frequency, in acrostic, in a random order, etc. However, the presentation of such tags in the tag cloud in such a manner may not aid the user in understanding the significance of the tags (i.e., why some tags have a larger font size than other tags) or the interrelation between these tags. Furthermore, the presentation of such tags in the tag cloud in such a manner may be not be visually appealing thereby adding further confusion.

As a result, the tags of a tag cloud are not currently presented in a manner that is visually appealing and that aids in the user's understanding of the tags in order to extract insight from the tag cloud.

BRIEF SUMMARY

In one embodiment of the present invention, a method for presenting tags of a tag cloud in a more understandable and visually appealing manner comprises retrieving tags of a tag cloud associated with an object. The method further comprises assigning the retrieved tags to parts of speech. The method additionally comprises generating, by a processor, combinations of the tags based on the parts of speech assigned to the tags. Additionally, the method comprises determining a layout to display the generated combinations of tags. In addition, the method comprises presenting the generated combinations of tags of the tag cloud using the determined layout.

Other forms of the embodiment of the method described above are in a system and in a computer program product.

The foregoing has outlined rather generally the features and technical advantages of one or more embodiments of the present invention in order that the detailed description of the present invention that follows may be better understood. Additional features and advantages of the present invention will be described hereinafter which may form the subject of the claims of the present invention.

DETAILED DESCRIPTION

The present invention comprises a method, system and computer program product for presenting tags of a tag cloud in a more understandable and visually appealing manner. In one embodiment of the present invention, tags of a tag cloud that are associated with an object (e.g., web page, a video) are retrieved. The retrieved tags are then assigned to parts of speech (e.g., verb, noun, pronoun, adjective, adverb, preposition, conjunction, interjection). Combinations of the tags are then generated based on the parts of speech assigned to the tags. For example, the combinations of the tags may be based on a template, such as <NOUN> <VERB> <ADJECTIVE>, <PRONOUN> <VERB> <ADJECTIVE>, <PRONOUN> is <ADVERB><VERB> and so forth. A layout to display the generated combinations of tags is then determined. Upon determining the layout to display the generated combinations of tags, the combinations of tags are then presented using the determined layout. Since the tags of the tag cloud are presented in a combination based on the parts of speech assigned to the tags, the tag cloud is more understandable and visually appealing thereby enabling the user to extract insight from the tag cloud.

In the following description, numerous specific details are set forth to provide a thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention may be practiced without such specific details. In other instances, well-known circuits have been shown in block diagram form in order not to obscure the present invention in unnecessary detail. For the most part, details considering timing considerations and the like have been omitted inasmuch as such details are not necessary to obtain a complete understanding of the present invention and are within the skills of persons of ordinary skill in the relevant art.

Referring now to the Figures in detail, FIG. 1 illustrates a network system 100 for practicing the principles of the present invention in accordance with an embodiment of the present invention. Network system 100 includes client devices 101A-101C (identified as “Client Device A,” “Client Device B,” and “Client Device C,” respectively, in FIG. 1) connected to a server 102 via a network 103. Client devices 101A-101C may collectively or individually be referred to as client devices 101 or client device 101, respectively. Client device 101 may be any type of computing device (e.g., portable computing unit, Personal Digital Assistant (PDA), smartphone, laptop computer, mobile phone, navigation device, game console, desktop computer system, workstation, Internet appliance and the like) configured with the capability of connecting to network 103 and consequently communicating with other client devices 101 and server 102.

In one embodiment, server 102 may be a web server configured to host websites. In one embodiment, server 102 is configured to receive a request from client device 101 to load a web page which is then transmitted to the requesting client device 101. In one embodiment, the requested web page may contain one or more tag clouds. Tag clouds are visual depictions that allow users to easily see the content of an object or tag source, such as the website itself or objects on the website, such as an article, video, etc. A tag cloud contains a set of related tags, where each tag is a keyword pertaining to the object or tag source. The tag cloud emphasizes the tags that are more popular or are associated with more frequently used keywords pertaining to the object or tag source, such as by increasing the tag's font size, font color, etc. The tags in the tag cloud may be hyperlinked to keywords within the tag source for the user's convenience. Such tags may be stored in a repository 104 connected to server 102. Repository 104 may also store a library of terms, where each of the terms is associated with one or more parts of speech. A description of the hardware configuration of server 102 is provided further below in connection with FIG. 2.

Network 103 may be, for example, a local area network, a wide area network, a wireless wide area network, a circuit-switched telephone network, a Global System for Mobile Communications (GSM) network, Wireless Application Protocol (WAP) network, a WiFi network, an IEEE 802.11 standards network, various combinations thereof, etc. Other networks, whose descriptions are omitted here for brevity, may also be used in conjunction with system 100 of FIG. 1 without departing from the scope of the present invention.

While FIG. 1 illustrates three clients 101A-101C, a single server 102, a single network 103 and a single repository 104, network system 100 may include any number of clients 101, servers 102, networks 103 and repositories 104. The embodiments of network system 100 are not to be limited in scope to the depiction of FIG. 1.

Referring now to FIG. 2, FIG. 2 illustrates a hardware configuration of server 102 (FIG. 1) which is representative of a hardware environment for practicing the present invention. Referring to FIG. 2, server 102 has a processor 201 coupled to various other components by system bus 202. An operating system 203 runs on processor 201 and provides control and coordinates the functions of the various components of FIG. 2. An application 204 in accordance with the principles of the present invention runs in conjunction with operating system 203 and provides calls to operating system 203 where the calls implement the various functions or services to be performed by application 204. Application 204 may include, for example, a program for presenting tags of a tag cloud in a more understandable and visually appealing manner as discussed further below in association with FIG. 3.

Referring again to FIG. 2, read-only memory (“ROM”) 205 is coupled to system bus 202 and includes a basic input/output system (“BIOS”) that controls certain basic functions of server 102. Random access memory (“RAM”) 206 and disk adapter 207 are also coupled to system bus 202. It should be noted that software components including operating system 203 and application 204 may be loaded into RAM 206, which may be server's 102 main memory for execution. Disk adapter 207 may be an integrated drive electronics (“IDE”) adapter that communicates with a disk unit 208, e.g., disk drive. It is noted that the program for presenting tags of a tag cloud in a more understandable and visually appealing manner, as discussed further below in association with FIG. 3, may reside in disk unit 208 or in application 204.

Server 102 may further include a communications adapter 209 coupled to bus 202. Communications adapter 209 interconnects bus 202 with an outside network (e.g., network 103 of FIG. 1) thereby allowing server 102 to communicate with client devices 101.

As stated in the Background section, currently, the tags of the tag cloud are presented in a predefined manner, such as in alphabetical order, in order of frequency, in acrostic, in a random order, etc. However, the presentation of such tags in the tag cloud in such a manner may not aid the user in understanding the significance of the tags (i.e., why some tags have a larger font size than other tags) or the interrelation between these tags. Furthermore, the presentation of such tags in the tag cloud in such a manner may be not be visually appealing thereby adding further confusion. As a result, the tags of a tag cloud are not currently presented in a manner that is visually appealing and that aids in the user's understanding of the tags in order to extract insight from the tag cloud.

The principles of the present invention provide a means for presenting tags of a tag cloud in a more understandable and visually appealing manner thereby enabling the user to extract insight from the tag cloud as discussed below in association with FIG. 3.

FIG. 3 is a flowchart of a method 300 for presenting tags of a tag cloud in a more understandable and visually appealing manner in accordance with an embodiment of the present invention.

Referring to FIG. 3, in conjunction with FIGS. 1-2, in step 301, server 102 activates the analysis on the tags for a tag cloud. In one embodiment, the analysis may be activated upon detecting a request from client device 101 to load a web page containing one or more tag clouds. In another embodiment, the analysis may be activated upon detecting a modification to a tag cloud. In another embodiment, the analysis may be activated upon the occurrence of an event (e.g., Sunday at 2:00 pm) or based upon metrics (e.g., threshold number of webpage views, threshold number of tags).

In step 302, server 102 retrieves the tags of a tag cloud associated with an object (e.g., a webpage, a document, a video, a folder, a multimedia application). For example, server 102 may retrieve the tags of a tag cloud associated with the web page requested by client device 101. For instance, users of client devices 101 may have tagged the website with keywords, such as “enjoyment” and “pure.” As a result, such tags (“enjoyment” and pure”) may be stored in repository 104 and retrieved by server 102. In another example, server 102 retrieves the tags of a tag cloud associated with a video to be displayed on the web page requested by client device 101. In one embodiment, the tags are retrieved from repository 104, such as via a web service or a Structured Query Language (SQL) query.

In step 303, server 102 assigns the retrieved tags to parts of speech, where the parts of speech may include a verb, a noun, a pronoun, an adjective, an adverb, a preposition, a conjunction and an interjection. For example, the term “smart” may be designated as an adjective; whereas, the term “smartly” may be designated as an adverb. In one embodiment, the parts of speech may be assigned to the terms (i.e., the tags) based on a library of terms, where each of the terms is associated with one or more parts of speech. In one embodiment, such a library of terms is stored in repository 104, where server 102 performs a look-up of the tag in the library of terms.

In step 304, server 102 sorts the tags assigned to the parts of speech based on tag weights. For example, the pronoun of “he/she” may be assigned a higher weight than the term “one” as the term “he/she” may provide more insight of the tag cloud versus the term “one.” In another example, action verbs may be weighted higher versus linking verbs or auxiliary verbs. In one embodiment, the weights associated to the tags may be based on the frequency of use of the tag by users of client devices 101 to describe the object.

In step 305, server 102 generates combinations of the tags based on the parts of speech assigned to the tags, including being based on the weight assigned to tags. For example, the tags with the highest weight for its associated parts of speech may be used in a combination prior to tags with a lower weight. Also, within that combination of tags, the tags with the highest weight may be emphasized, such as by increasing that tag's font size, font color, etc. in comparison to the other tags in the combination.

In one embodiment, such combinations are based on a template, such as <NOUN> <VERB> <ADJECTIVE>, <PRONOUN> <VERB> <ADJECTIVE>, <PRONOUN> is <ADVERB><VERB> and so forth. In one embodiment, the number of parts of speech to be utilized in a particular combination of tags as a template is user selected. For example, the user may select three parts of speech (e.g., noun, verb, adjective) or may select four parts of speech (e.g., noun, verb, adjective, adjective) to be used in a combination of tags as a template. In another embodiment, the user may select the number of parts of speech, as well as which parts of speech, are to be utilized in a combination of tags as a template via sliders. In one embodiment, the template may include different combinations of parts of speech.

In one embodiment, server 102 utilizes natural language processing using a natural language library to generate the parts of speech into a cohesive entry (or phrase). That is, natural language processing may be utilized by server 102 to ensure a combination of the tags that is understandable to the users of client devices 101 as well as to provide more insight into the object. In another embodiment, server 102 inserts additional terms in the tag combination, such as “is,” or related parts of speech (e.g., he, I, one) to generate the parts of speech into a cohesive entry, i.e., to ensure that the combination of the tags is understandable to the users of client devices 101 as well as to provide more insight into the object.

For example, suppose that a user of client device 101A tags an object as “enjoyment” and “pure.” Suppose that a user of client device 101B tags the object as “likeable” and “pager.” Suppose further that a user of client device 101C tags the object as “improve” and “pure” and “Roger.” In response to a user of client device 101 loading the object, such as a webpage, server 102 retrieves the tags associated with the object. The term “Roger” may be assigned the part of speech of noun. The term “pure” may be assigned the part of speech of adjective. The term “enjoyment” may be assigned the part of speech of noun. The term “improve” may be assigned the part of speech of verb. The term “pager” may be assigned the part of speech of noun. The term “likeable” may be assigned the part of speech of adjective. Since the term “pure” was tagged twice as opposed to the other terms that were tagged once, it may be assigned a higher weight. As discussed above, server 102 may utilize natural language processing using a natural language library to generate the parts of speech into a cohesive entry. Furthermore, server 102 may insert additional terms in the tag combination (“is,” “has”) or related parts of speech (e.g., “he,” “I,” “one”) to ensure that the combination of the tags is understandable to the users of client devices 101 as well as to provide more insight into the object. As a result, server 102 may generate the combinations of “Roger has pure enjoyment,” “Roger improves this pager,” “Roger improves the enjoyment,” etc. In the example of the combination of “Roger has pure enjoyment,” since the term “pure” has a higher weight versus the other terms, the term “pure” may be emphasized by having its font size and/or font color enlarged. By including terms around the emphasized term “pure,” the user has a better understanding as to the significance of the term “pure” as well as why it was emphasized thereby providing more insight into the tag cloud. In other words, by including a combination of tags based on the parts of speech assigned to the tags, and emphasizing the tag(s) within that combination based on frequency of use, etc., the tags of the tag cloud are presented in a more understandable and visually appealing manner thereby enabling the user to extract more insight from the tag cloud.

In step 306, server 102 determines a layout to display the generated combinations of tags. For example, a layout of acrostic may be utilized based on the combination of tags. Other examples of arrangements include a sequential, circular, clustered and alphabetical-based arrangement. In connection with determining a layout to display the generated combinations of tags, the tags within a combination of tags that have a higher weight, such as being used more frequently, may be displayed in a manner to highlight the greater weight, such as by increasing the tag's font size, font color, etc. for that combination of tags.

In step 307, server 102 presents the generated combinations of tags of the tag cloud using the layout determined in step 306. Since the tags of the tag cloud are presented in a combination based on the parts of speech assigned to the tags, the tag cloud is more understandable and visually appealing to the users of client devices 101.

In step 308, a determination is made by server 102 as to whether server 102 received any feedback, such as from users of client devices 101, regarding the relationships between the tags. For instance, a user may indicate that the combination of tags is inappropriate.

If there is no feedback regarding the relationships between the tags, then server 102 continues to determine whether it received any feedback in step 308.

If, however, server 102 received feedback regarding the relationships between the tags, then, in step 309, a determination is made by server 102 as to whether a combination of the tags is to be modified. For example, if the feedback from the users of client devices 101 indicates that the combination of “Roger has pure enjoyment” is not accurate, not appropriate, not understandable, not preferable to other combinations of tags in describing the object, etc., then such a combination may be modified, whether in terms of the particular tags used in the combination and/or the manner in which the tag combination is displayed, such as decreasing the font size of particular tags in the tag combination or relocating the location of the tag combination on the web page displayed to the users of client devices 101.

If server 102 is to modify a combination of the tags, then, in step 310, server 102 modifies the generated combination of tags, such as modifying the combination of tags (whether in one or more combinations) and/or the manner in which the combination(s) are displayed. Upon modifying the combination(s) of tags, server 101 determines a layout to display the combinations of tags in step 306.

If, however, server 102 is not to modify a combination of the tags, then server 102 continues to determine whether it received any feedback in step 308.
